Separation Rolls Product Details
The MPI Separation Roll is strategically installed as the head pulley in a conveyor system. As material travels along the belt, it enters the magnetic field generated by the pulley. Ferrous tramp metals—such as nails, bolts, wire, and scrap—are immediately attracted and held tightly to the conveyor belt surface. While the clean, contaminant-free product is discharged from the top of the pulley at the end of the conveyor, the tramp iron remains attached to the belt as it wraps around the pulley. Upon reaching the underside of the roll, the tramp metal moves out of the magnetic field and falls freely into a designated chute or collection bin. This process runs continuously and automatically, with no need for operator intervention, ensuring a safer, cleaner material stream and reduced wear on equipment.
Separation Rolls Specifications
Magnet Circuits:
Axial (A)
This magnet circuit provides alternating north and south magnetic poles around the roll diameter, providing optimum magnetic field “reach-out” and a consistent magnetic pole across the roll width. This magnet design is ideal for capturing medium to larger types of tramp metal in moderate to deep product flows on the conveyer belt.
Salient (S)
This magnet circuit provides a large number of highly concentrated magnetic poles at intervals across the roll width and a consistent magnetic pole around the roll diameter. This magnet design is ideal for capturing small to fine types of tramp metal in shallow product flows on the conveyer belt.
Radial (R)
This magnet circuit provides a lower number of highly concentrated magnetic poles at intervals across the roll width as compared to a SALIENT design, improving magnetic field “reach-out” and a consistent magnetic pole around the roll diameter. This magnet design is ideal for capturing small to larger types of tramp metal in shallow to moderate flows on the conveyer belt.
Magnet Face Options:
Flat Stainless Steel (FS)
This is the most economical option offered and provides a durable non-magnetic stainless steel belt running surface.
Flat Stainless Steel with Centering Track Bar (FSTB)
This is an economical way to provide a degree of center belt tracking, without the expensive costs of crowning.
Crowned Stainless Steel (CS)
This is the most expensive option and offers a durable non-magnetic stainless steel-belt running surface with a belt centering crown.
Crowned Vulcanized Rubber (CVR)
This option offers both an economical way to provide a belt-centering crown design and improved belt traction.
Crowned Vulcanized and Lagged Rubber (CVRL)
This option can be added to any vulcanized rubber roll where belt traction is critical. It is available in a variety of standard patterns, such as herringbone, diamond, etc.
